Coupled Modulation Separation for Gear Severity Evaluation Based on Vibration Mechanism and Speed Extraction

open access: yesMachines
An abundant gear fault modulation signal is closely related to the gear fault type, especially to the gear fault severity. However, the modulation signal simultaneously includes coupled frequency modulation and amplitude modulation, which hinders the ...

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Modulation of Wnt signaling [PDF]

open access: yesCommunicative & Integrative Biology, 2011
The Phylum Cnidaria diverged from the line leading to the Bilateria approximately 630 million years ago, making them well positioned to provide insights into the diversification of eumetazoan body plans and the molecular mechanisms by which body patterning is controlled.1,2 Our recent paper3 focused on Wnt-mediated axis formation during both ...

Signal regeneration techniques for advanced modulation formats [PDF]

open access: yes
We review recent results on all-optical regeneration of phase encoded signals based on phase sensitive amplification achieved by avoiding phase-to-amplitude conversion in order to facilitate the regeneration of amplitude/phase encoded (QAM ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

PWM-based PPM format for dimming control in visible light communication system [PDF]

open access: yes, 2012
We report simulation results of pulse width modulation (PWM)-based pulse position modulation (PPM) signal format for visible light communication systems. For simultaneous operation of data transmission and dimming control, PPM data format is added to PWM

Cochannel measurements for amplitude companded SSB voice communications [PDF]

open access: yes, 1987
The authors examined certain aspects of a cellular radio system that are closely tied to the modulation method used, namely, channel sounding, interference immunity, signal quality, information transfer rate, and channel transparency.
